Acquired uterine arteriovenous malformation treated with superselective embolization: Case report.

Acquired uterine arteriovenous malformation is a rare condition, sometimes provoking abnormal life-threatening uterine hemorrhage. Here, we present the case of a 30-year-old healthy woman who developed heavy vaginal bleeding after dilatation and suctioning of the placenta 1 month after the delivery of a nonviable fetus. An ultrasound was performed which showed the appearance of a large exacerbation of a vessel with positive fetal sounds, normal cardiac movement, and normal morphological analysis. The patient was successfully treated with unilateral superselective embolization, distal to the ovarian supply, maintaining normal supply to the uterus and ovaries restoring normal menstruation, and showed complete resolution of the arteriovenous malformation.

Single-Institution Experience with Selective Internal Radiation Therapy (SIRT) for the Treatment of Primary and Secondary Hepatic Tumors.

PURPOSE: We aim to provide results of the real-world experience of a single center in Lebanon on the use of radioembolization to treat liver-only or liver-dominant tumors.  Methods: This retrospective review included patients who were evaluated for radioembolization between January 2015 and June 2017 and who had a lung shunt fraction of 20% or less. Tumor responses were determined using the response evaluation criteria in solid tumors (RECIST). RESULTS: Of the 23 Arab patients with a median age of 64 years (range, 36-87 years), eight had hepatocellular carcinoma, four had cholangiocarcinoma, and 11 had liver-only or liver-dominant metastases from other primary cancers. Most (n=17) had multifocal lesions, and 13 had a history of branched (n=8) or main (n=5) portal vein thrombosis. When appropriate, the gastroduodenal artery and middle hepatic artery were embolized for consolidation of radiotherapy; 18 patients required arterial coil occlusion, two had their cystic artery occluded, and one developed cholecystitis, which was successfully treated with antibiotics and supportive care. Another patient developed a post-radioembolization complication-a peptic ulcer unrelated to arterial reflux of microspheres because both the gastroduodenal and right gastric arteries were occluded. The median time to progression was seven months (range, 3-36 months), and median overall survival from radioembolization was 12 months (range, 3-40 months). Tumor responses included five complete responses, 13 partial responses, one stable disease, and four cases of progressive disease.  Conclusion: Performing radioembolization in a non-referral, private center in Lebanon resulted in good patient outcomes with few complications.

Limbic encephalitis associated with tuberculous mediastinal lymphadenitis.

INTRODUCTION: Limbic encephalitis represents an autoimmune disorder that is commonly associated with malignancies. It is also seen in association with infectious or systemic autoimmune diseases. The literature reports two case reports of limbic encephalitis associated with tuberculosis. CASE REPORT: We report the case of a 42 year-old male referred to our clinic for a non-resolving pneumonia. He was found to have a limbic encephalitis associated with mediastinal tuberculous lymphadenitis. The diagnosis was made on a needle aspirate from a mediastinal lymph node obtained through endobronchial ultrasound. A paradoxical radiological progression was noted during therapy. He was successfully treated by anti-tuberculous drugs with clinical and radiological improvement. CONCLUSION: Limbic encephalitis is associated with tuberculosis and should be included as part of the central nervous system involvement with tuberculosis. Endobronchial ultrasound has been shown to be useful in the diagnosis of mediastinal tuberculous lymphadenitis.

Patients with Isolated Focal Right Ventricular Dyskinetic Segments: Toward a Better Understanding of This Cohort.

BACKGROUND: The 2010 revised Task Force criteria for the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) provided guidance for the classification of patients as definitive, borderline or possible ARVC. However, many patients with clinical suspicion for ARVC have isolated RV dyskinetic segments only and partly meet cardiac magnetic resonance (CMR) imaging criteria. This subgroup of patients and the implication of this imaging finding remain not well defined. METHODS: There were 65 consecutive patients with clinical suspicion for ARVC who were referred for CMR between 2015 and 2017. The presence of fatty infiltration and fibrosis were assessed using T2 imaging and myocardial delayed enhancement sequences, respectively. RV wall motions, volumes and ejection fraction (EF) of all patients were re-analysed and quantified. Available data on family history, Holter findings, and electrocardiograms were also reviewed. RESULTS: There were 5 patients (7.7%) that fulfilled major CMR criteria for ARVC: 4 were classified as having definitive ARVC; and 1/5 as borderline. There were 33 patients with no RV dyskinetic segments: none were classified as having definitive or borderline ARVC; 4/33 were classified as possible ARVC, leaving 29/33 as normal or no ARVC. Finally, there were 27 remaining patients (41.5%) with isolated RV dyskinetic segments: 1/27 was classified as definitive ARVC; 4/27 as borderline; 8/27 as possible; leaving 15/27 as indeterminate. Compared to control, those with isolated RV dyskinesia (including the subgroup labelled as indeterminate 15/27) had more abnormal RVEF, larger RV end-diastolic volume index (82 ± 12 mL/m² vs. 72 ± 12 mL/m², p-value 0.0127), and a trend for higher odds of dilated RV (odds ratio 3.0 [0.81-11], p-value 0.09). CONCLUSIONS: Among patients with a clinical suspicion for ARVC, almost 40% had isolated focal RV dyskinetic segments with the majority remaining unclassified. This cohort had more RV dilation and abnormal EF compared to control.

Calcaneus Metastasis from Follicular Thyroid Carcinoma 12 Years after Total Thyroidectomy.

We report the case of a sixty-eight-year-old female patient who presented for left ankle pain; X-rays and MRI showed a benign calcaneal cyst, found to be delayed distant metastasis from primary papillary thyroid carcinoma. Patient required surgical excision of the cyst. Results of histological examination showed metastatic papillary thyroid carcinoma. The patient underwent total thyroidectomy 12 years prior to presentation, with the same pathology. Postoperatively, she was treated with radioactive iodine. At 10-year follow-up post calcaneal mass excision, she was found to have a right proximal tibial mass and found to be recurrent with the same pathology. This case reports a rare condition that will be taken into consideration in bone metastasis with thyroid cancer.

Novel management of ovarian vein thrombosis: A case report.

Ovarian vein thrombosis (OVT) is a rare serious diagnosis especially if extending to inferior vein cava (IVC). We present a case of 36-year- old female who was diagnosed with right OVT reaching the inferior vein cava following a supra-cervical hysterectomy that was performed in the postpartum period due to excessive bleeding from uterine fibroids. Using the new generation anti-coagulant "rivaroxaban" for six months followed by maintenance regimen of aspirin and sulodexide, complete resolution of the clot was noticed without any adverse event while using this regimen. This is the first OVT case which is completely treated with rivaroxaban without any adjunct invasive modality.
